4 Claims.

This invention relates to an. oiling'zduevice and -,particularly to that type of :oilers in which an roiling "ring is carried loosely over a "shaft to be revolved thereby in order to lift oil from a lower -reservoir and carry the :oil up on the ring into rcontact with the shaft at'ashaft bearing. The invention :resides particularly in the means for :forming the ring, in parts .and securing the parts one {to the otherso as to present a durable structure which will not work loose nor ride con the shaft in .a fixed position. Further'objects and '.ad\,'antages of the inventionsuch as cheapness in cost of manufacture, durability, and ease of assembly, will become apparent to those versed in the art in the following s-descriptionof the invenvtion as illustrated'in the accompanying drawing, .inwhich Fig. :1 is a section through a bearing showin the invention applied thereto;

Fig. 3, the formed blank in top plan View;

Fig. 4, a side elevation of the ring in finished form;

Fig; '5, a bottom plan view of the ring on an enlarged "scale and in partial section; and

6, a detail in top plan viewof a modified form of joint- 'Likercharacters of reference indicate like parts -throughout the several views :in the drawing.

, Referring rflISt to figs. =2 and .3, a, blank ring preferably :having .a rectangular cross section is initially formed to haveicircular-end portions it] and 1'! with interconnecting straight portions 12 and L3. The lengths or -:the straight portions 1-2 and i3 are madez'to besuchthat when in the finished assembled ring, that ring will be completely circular as will hereinafter appear.

(These fiat portions i2 and i3 are cut and shaped to havethe configurations as indicated in :Fig. 3 wherein-opposing lips M and i5 arepre- .sented with-their underfaces cut'back'on angles, preferably 45 degrees and thematerial'is removed between these lips :M and .for a distance in -from the face A of the blank. This removedportion leaves a slot across the face of the ring on eachof the flat portionsiz and. Inthe bottom l of this slot are out .a number-of teeth I6 on-the sideadjacent the lip 1M and i? ion-the other side adjacent the lip 15 with a deeper portion of the "slot extending across the flat portions centrally of the space between the lips M and "i5 and between the sets of teeth It and l-l as indicated in Fig. 3. The heighttof the. teeth it and ii! .in relation to their root and outside terminating rend planes madeito beisuch that equal portions of the teeth lie on each side of the central plane midway between the faces A and B of the blank. The

shape of the teeth It and I1 may assume a number of forms, one particular form working to adin side vantage is the square tooth as herein indicated. Also the number of teeth in each set while necessarily being identical may vary from one or more as may be desired and particularly depending upon the size of the ring being made, more teeth being desired with larger rings than in smaller rings.

The foregoing operations'of forming the lips 14 and 'tSandthe teeth t6 and i l have been made in the. ring'downwardly from the face A. Another operation isperformed on-the ringblank from the face 13 which consists of cutting a 90 degree groove it across each of the portions [2 and ii) on their,

'face :23 sides, these grooves being centered transverselyacross the rings in relation to the spacing between the ends of the lips M and. I5. This notch E8 is cut sufliciently deep as will just sever the blank into-the two portions in and 1 I. Thus Y the blank is formed intotwo identically shaped portions H3 and l l separated one from the other. :One of these portions is reversed end for end in relation to the other'portion. For example, when thetwo portions Ill and ii are just cutthrough, I

Fig. 2,-t'here are l'eft-theifree ends 0 andD on the portion 5H) and 'E and -"F'on the :portion H.

fl hen'in order'to assemble the two portions in and l l, the portion i0 islheldin its'orig'inal position as indicated in Figss2and 3 torb-ring'the ends F and E'into juxtaposition. with the ends C and'D respectively. :In bringing these ends one toward the other, rthegend C is brought above end F and I likewise the end B is brought above the end F and the two parts pushed in parallel alignment one inrelation .to'the other so as to bring respective end :portions under respective lip portions with the respective teeth "H5 and i1 sliding into mesh vendto end. ;In other words,-one ring portion is moved in relation to'the'other as'suggested in-Fig. 4 in moving thelring portion in relatively from the :dash line position to fthessolid line position in-relation to the ring 'portion 1 i. When these two portions are thusbrought together to formone-continuous ring in effect, they are preferably locked-in somesuch manner as'by soldering or by employing screws t9 and 2t screwthreadedly interengagingsthe two ring portions-Fig. 5.

slope'of the sides ofthe notch-l8, Fig. 3, must be identical with that of the under sides of the lips I M and I5 since these faces of the notch l8 are the ones that set against the under faces of the lips cut inthat relation, one set with the. other; as

will permit the intermeshing from their ends of these interlocking teeth l6 and I! the ring portions cannot pull apart one from the other circumferentially and by reason of the ends lap- I In order to secure this particular means for interengaging'the ends of the ring portions, the

, I4 and 1-5. Likewise the teeth "Sand 1'! must be I ping under the lips l4 and l5, the ring portions cannot be displaced one from the other laterally and the only permissible movement is that chordal locked ring that will not work loose in operation regardless of the severity of vibration or speed of the shaft 2| which may carry the finished ring. However, in some installations, it may be diflicult to assemble the two portions of the ring about the shaft 2i due to limited space and for such cases, the type of joint as indicated in Fig. 6 may be employed. In this form, not only are the lips I 4 and I5 undercut on 45 degree angles as are the respective end portions of the ring segments, but the teeth 22 and 23 are likewise cut to have 45 degree sloped faces so that the ring segments may be brought to alignment end to end to have the end G, for example, initially abut the end of the lip I4 and thereby be carried down the 45 degree slope to bring all of the other elements into alignment, this being permissible since all of the faces of the teeth and of the ends and lips are cut in respective parallel planes permitting and directing the final intimate contact therebetween, this movement being suggested by the initial dash line position of the one segment progressing to the solid line position, Fig. 6. It is understood of course that in this form, Fig. 6, the various elements such as the lips and teeth are cut in the respective ends in identical relationship one with the other in respect to the central longitudinal plane through the ring. This form may likewise be locked together in any one of many ways, one particular way being by means of a screw interengaging the two ends to prevent their shifting.

It is to be understood that the two ring portions are semi-circular with the inner ends of the flat portions l2 and I3 joining the portions on the diametrical lines of the curved portions. Then when the ring portions are assembled to form the complete ring, the inner periphery of the ring approaches very nearly a true circle. In

nients end may be freelyentered down on the other and then the two ends forced and wedged home to the continuous periphery positions. In this manner, a secure interlocking is had without use of the screw 20.

While I have herein shown and described my invention in the best form now known to me, it is obvious that structural changes may be employed without departing from the spirit of the invention such as change in slope of the faces of the teeth and lips and segment ends, and I therefore do not desire to be limited to that precise form beyond the limitations as may be imposed by the following claims.

I claim:

1. A two piece oiling ring formed of symmetrical parts, each part comprising a semi-circular open end portion terminating with short connecting ends, each end being formed to have a. notch cut back from the terminal end to leave an under cut shoulder at the inner end of the notch, at least two grooves formed transversely across the notch faceto define a tooth thereacross, and each end being bevelled on its side opposite said notch to a slope conforming to that of the undercut face of said shoulder, said ring parts being assembled to have the bevelled end of one portion engaged under the shoulder of the other and said teeth meshed one between the others.

2. A two piece oiling ring formed of symmetrical parts, each part comprising a semi-circular open end portion terminating with short connecting ends, each end being formed to have a notch cut back from the terminal end to leave an undercut shoulder at the inner end of the notch, at

least two groovesformed transversely across the engaged under the shoulder of the other and said teeth meshed one between the others, said notch in each end being at the juncture between the circular and straight portions of the ring parts whereby, upon assembly, a substantially complete circular inner periphery is formed, said grooves being parallel to the diameter of the assembled ring.

3. A two piece oiling ring formed of symmetrical parts, each part comprisinga semi-circular open end portion terminating with short straight ends, each end being formed to have a notch cut back from the terminal end to leave an undercut shoulder at the inner end of the notch, at least two grooves formed transversely across the notch face to define a tooth thereacross, and each end being bevelled on its side opposite said notch to a slope conforming to that of the undercut face of said shoulder, said ring parts being assembled to have the bevelled end of one portion engaged under the shoulder of the other and said teeth meshed one between the others, said notches and said grooves being formed to have forty-five degree slopes, whereby the ring parts may be moved into assembly by pushing the ends of one part along over the ends 'of the other part normally ofthe diameter of the finished ring to cause the slopes of the undercut notch ends to direct the ends laterally one against the other into snug seating arrangement to form a continuous ring without offsets at the part junctures.

4. A two piece oiling ring formed of symmetrical parts, each part comprising a. semi-circular open end portion terminating with short connecting ends, each end being formed to have a notch cut back from the terminal end to leave an undercut shoulder at the inner end of the notch, at least two grooves formed transversely across the notch face to define a tooth thereacross, and each,

end being bevelled on its side opposite said notch toa slope conforming to that of the undercut face of said shoulder, said ring parts being assembled to have the bevelled end of one portion engaged under the shoulder of the other and said teeth meshed one between the others, the undercut faces'of said shoulders being tapered in each instance inwardly and toward the opposing shoulder, whereby the two parts may be seated in wedging engagement.
